1.Given the following declarations, evaluate the boolean expressions labelled a-f below as either true or false: (Section 3.1-3.2) int age = 19; double weight = 180.0; int length = 4; int width = 5; String myString = \"Four score and seven years ago\"; String mySubstring = myString.substring(0,4); char letter = \'v\'; a.age >= 21 b.length * width == 20 c.weight / 2 >= 95.0 d.myString.equals(\"When in the course of human events\") e.myString == \"Four score and seven years ago\" // HINT: did you read page 92? f.mySubstring.equals(\"Four\");

Solution

Answer:

int age = 19;

a) age > = 21 it is False as the age declared above is 19 which is less than 21.

int length = 4; int width = 5;

b) length * width = 20 , it is TRUE because 4*5 = 20 which is of type int.

double weight = 180.0;

  c) weight/2 > = 95.0 it is FALSE because 180.0/2 = 90 not 95
